 A library to handle [Hangul](https://en.wikipedia.org/wiki/Hangul) (Korean) characters, in modern JavaScript.
 
+## Deprecation Notice
+
+Please note that `@toss/hangul` has been deprecated. We have transitioned to a new package, `es-hangul`, which offers improved functionality and performance.
+
+### Recommended Actions:
+
+- Update your dependencies to use `es-hangul`.
+- Refer to the `es-hangul` documentation for new features and implementation details.
+
+Thank you for your continued support and understanding.
+
+## Documentation
+
+For more information about `es-hangul`, please visit [es-hangul documentation](https://es-hangul.slash.page/).
+
 ## Motivation
 
 In Korean services, there are cases where we have to handle Hangul characters in a sophisticated way. For example, when searching among Korean strings, most Koreans expect to search `토스` with `톳`, or `토스` with `ㅌㅅ`.
